硫酸镁:0.024—0.025份,硫酸铵:0.058—0.06份,磷酸二氢钾:0.048—0.05份,氯化钙:0.018—0.02份,硝酸钠:0.048—0.05份,柠檬酸铁铵:0.68—0.7份,浓度为10%的氢氧化钠:0.029—0.3份,去离子水:97.9—98.8份。
上述的用于油田污水处理系统的铁细菌培养基,其特殊之处在于:由以下物质按照重量份组成:
硫酸镁:0.0245份,硫酸铵:0.059份,磷酸二氢钾:0.049份,氯化钙:0.019份,硝酸钠:0.049份,柠檬酸铁铵:0.69份,浓度为10%的氢氧化钠:0.1645份,去离子水:98.35份。
与现有技术相比,本发明敏度高、准确度高,能够快速便捷检测油田污水中细菌含量。
具体实施方式
下面结合具体实施方式对本发明进行详细说明。
本发明由以下物质按照重量份组成:
硫酸镁:0.024—0.025份,硫酸铵:0.058—0.06份,磷酸二氢钾:0.048—0.05份,氯化钙:0.018—0.02份,硝酸钠:0.048—0.05份,柠檬酸铁铵:0.68—0.7份,浓度为10%的氢氧化钠:0.029—0.3份,去离子水:97.9—98.8份。
本发明由以下物质按照重量份组成:
硫酸镁:0.0245份,硫酸铵:0.059份,磷酸二氢钾:0.049份,氯化钙:0.019份,硝酸钠:0.049份,柠檬酸铁铵:0.69份,浓度为10%的氢氧化钠:0.1645份,去离子水:98.35份。
实施例1:
本发明由以下物质按照重量份组成:
硫酸镁:0.024份,硫酸铵:0.058份,磷酸二氢钾:0.048份,氯化钙:0.018份,硝酸钠:0.048份,柠檬酸铁铵:0.68份,浓度为10%的氢氧化钠:0.029份,去离子水:97.9份。
按照上述比例配比各物质,通过以下步骤进行制备:
(一)、配制:
a、准备好干净干燥的玻璃器皿及所用的试剂,试剂必须符合生物试剂的要求且在有效期内;
b、根据培养基配制总量及配方计算各试剂的用量,用量筒准确量取1000mL蒸馏水,称量过程中使用精度为0.0001份的电子分析天平;
c、按配方中试剂的先后顺序用电子分析天平准确称量各种试剂,在100mL小烧杯中加入1000mL量筒中的蒸馏水完全溶解,转入1000mL烧杯中,将每个小烧杯冲洗3~5次,将冲洗液转入1000mL烧杯中;
d、待1000mL烧杯中全部试剂完全溶解后,加量筒中剩余的蒸馏水至大烧杯中;
e、用吸量管吸入混匀的培养基溶液滴在精密pH值试纸上,测定培养液的pH值,用10%的NaOH溶液调节pH值,调节过程中逐滴加入10%的NaOH溶液,边加边搅拌,防止局部碱度过高破坏营养基成分,并不时用pH试纸测试,直到pH值为7.0为止;
(二)、培养基的分装和灭菌
a、铁细菌培养基在分装前,应准确移入9mL铁细菌培养基溶液至10mL玻璃瓶中,然后加盖并封口;
b、将上述分装好的铁细菌培养基测试瓶分层放入高压蒸汽灭菌器内,瓶与瓶之间应留有空隙,封盖,将压力设定在0.145MPa、温度为126℃下灭菌30min左右,灭菌完毕后让其自动回压至常压,打开放气阀并开盖,冷却至常温,取出细菌培养瓶,检验合格后待用。
与现有技术相比,本发明的有益效果:
(1)铁细菌培养基对铁细菌的识别灵敏度高,培养基颜色变化明显,检测过程中易于观察。
(2)铁细菌培养基对铁细菌的识别准确度高,检测过程中平行样之间的差别小。
(3)铁细菌培养基对铁细菌的识别时间短,最终识别时间为3~5天,比目前市场上的同类产品时间缩短了2天。
